Statement I highlights the advantages of using concrete vis-a-vis bitumen and from if we know that concrete is supreme in every aspect to bitumen and hence it should be used to builds roads. Hence, I is strong.
Statement II gives a similar arguments as in the above case but favouring bitumen. Hence, II is also strong.However, both I and II contradict each other and hence they cannot both be strong at the same time. Hence, either I or II is strong but not both.
